Three years ago, I used to run my USRP1-based radio astronomy software for months at a time with no issue. In the last year or so, I've been unable to maintain those kinds of uptimes with either USRP1 or USRP2, which I ascribe to fundamental changes in Gnu Radio, but I haven't been able to put my finger on exactly which flow-graphs will "wedge" after a few days, and which ones will keep going and going. I have one flow-graph that uses the USRP2 at low bandwidths (400Ksps or so) that seems to be able to run forever. Another, similar flowgraph, will tend to "wedge" after a few days. I also have a flow-graph that uses an ALSA source and sink, and it can only run for a few days before "wedging". I think the USRP *hardware and drivers* are perfectly capable of running forever, but the current Gnu Radio seems to have issues that I haven't been able to pin-point with long-running applications. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org |
